Help submitting Exercise Tracker project

Tell us what’s happening:
I just finish my project and it runs perfect, and even I submitted, but when I go to claim my certificate about APIs and Microservices it does not appear as finished. I submitted it again and again but it is the same.

I do not know what to do, please help me
here is my code if you want to see it, it works perfectly and as I said the site accepted it but it is like it doesn’t save the record

Your code so far
